Frequently Asked Questions

Who should come in for a test?

All dental patients treated at the Southeast Dental Center, 3653 SE 34th Ave in Portland, between May 11 and May 24. Except, clients who visited our Baby Day dental clinic during these dates are NOT affected because no dental instruments are used with these clients.

How many people may be impacted?

Up to 18 individuals may have been exposed out of 524 individuals treated at Southeast Dental Clinic during the period of time. Because there is no way to know for sure which patients had contact with affected instruments we are recommending testing to all patients who visited the Southeast dental clinic during those dates.

How could patients have been exposed to blood-borne illnesses?

Providers may have used a hand instrument that was not fully sterilized per procedures.

What are the possible infections?

Hepatitis B, hepatitis C, and HIV.

How much does the blood test cost?

The County will provide blood tests, free of charge to patients.

What symptoms am I likely to have?

The only way to be sure you were not possibly exposed is to have the blood test, so we urge you to come into to have the test. The outcome of these tests will help us answer any questions you may have about possible symptoms you are experiencing.

How serious is the risk of infection?
All instrument packets go through a disinfection process and a sterilization process. The disinfection process was ​completed​. Regarding the sterilized process, the state requires one step to verify that instruments have been sterilized, while some agencies conduct multiple steps. A few, including Multnomah County, complete three redundant steps to ​verify​ sterilization. Two of those steps were verified. One step in the documentation could not be verified. Multnomah County consulted with the federal Centers for Disease Control and Prevention, which assessed the risk of infection from these instruments as "zero or close to zero." The county notified patients who could potentially have been exposed, however, out of an abundance of caution and in the of spirit of transparency.
